One great fanfic could be 'The Bonds Among Them'. It focuses on the complex relationships between Zero, Kaname, and Ichiru. It shows how their different personalities interact and how they deal with the challenges in their vampire - hunter world. It's really interesting to see how the author weaves their stories together.
One characteristic is the exploration of the complex relationship between Kaname and Zero. In these fanfictions, the authors often delve into their shared history and the underlying tensions. Another aspect is the emotional depth. Since Yaoi focuses on male - male relationships, there's often a strong emphasis on the characters' feelings for each other, which can range from intense love to bitter rivalry.
A lesser - known but really good fanfiction is 'Soulmate's Redemption'. Here, the story focuses on how their soulmate relationship helps them both overcome their past traumas. It's a more introspective piece that really digs into the psychological aspects of their characters.
I like 'A New Dawn for Kaname and Zero'. In this fanfic, it focuses on how they both have to overcome their own inner demons. Kaname's past and his responsibilities as a pureblood vampire are explored, and Zero's struggle with his own vampire side is also a central theme. Their relationship develops in a very natural way as they support each other through these difficult times.
The appeal lies in the contrast between the two characters. Zero is often seen as brooding and conflicted, while Kaname is more mysterious and powerful. A fanfic that pairs them can explore the chemistry that might exist between such different personalities.
Love and friendship are important themes. Despite their differences, there could be a sense of friendship or even a form of love developing among them. It's a complex love, not just romantic love. It could be the love of comradeship, or a sense of understanding and acceptance. Also, the theme of redemption might be present. Maybe one of the characters is seeking redemption for past actions and the others play a role in that process.
Love triangle is a very common theme. With Yuki being the center of attention for both Kaname and Zero, there's a constant tug - of - war for her affection. Another theme is the struggle between different vampire clans and the role these three play in it.
There are quite a few. I've come across some where the author really plays up the tension between them. It might start with a chance encounter and then build on the mutual attraction and the problems that come with it, like the differences in their vampire - hunter backgrounds. They could be in a situation where they have to work together despite their initial animosity.
The plot is crucial. It could be a story that explores their relationship in a unique way, perhaps in a different setting than the original. Maybe it's a story where they have to overcome some great challenges together, which would add depth and excitement to the fic. Also, good writing style, with proper grammar and engaging language, can make a fanfic really stand out.
The setting of the wedding is also important. It could be in a place that has significance to both of them, like the place where they first met or a place that represents their new unity. Also, the clothing they wear. Kaname might be in a traditional vampire - elegant and dark - while Zero could be in something that combines his hunter roots with a new, more accepting style for his relationship with Kaname.
